Walmart grocery pickup

I've been using walmart grocery pickup for a couple months now. My family and I sat down for a good while last night, as we always do to decided our weekly grocery order. I placed my order and set it for today for pickup. I got an email and an alert from walmart grocery a few hours ago saying they couldn't fulfill my order and had canceled it. No idea why, I tried calling the store several times and I've got no answer. I'm assuming because of the Coronavirus. Anyone know if Walmart has stopped doing the grocery pickup for a while? If that's the case they really should fix the walmart app so the order can't be placed at all. It took us a good while to make that grocery order, all for nothing. Ugh.

UPDATE: I finally got someone on the phone. She said the grocery system is having issues today so they canceled all orders after 2PM. She also said the stores shelves are looking pretty bare right now because everyone is panick shopping. Ugh.
